关于#python#的问题，如何解决？

怎么修改利用turtle库绘制七段数码管，显示当前日期及学生基本信息，包括学号、姓名？
感觉我的输出结果并不理想， 求指教。

import turtle
import random
import datetime


# 生成验证码
def generate_code(length):
    all_chars = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
    code = ''
    for i in range(length):
        index = random.randint(0, len(all_chars)-1)
        code += all_chars[index]
    return code


# 写入学生信息到文件
def write_student_info_to_file(student_info):
    with open('student_info.txt', 'w') as f:
        f.write(student_info)


# 从文件中读取学生信息
def read_student_info_from_file():
    with open('student_info.txt', 'r') as f:
        student_info = f.read()
    return student_info


# 绘制七段数码管并显示当前日期和学生基本信息

你是不是不知道什么是7段数码管，先百度图片里搜一下看看到底长什么样子，再代码绘制它
